The previous versions before Windows update

When Windows 98 was in use, Microsoft released the critical update notification tool/utility. This would run in the background. When a critical update was available, the user would get notified. The tool would conduct a check every 5 minutes and also when the internet explorer was opened. Through this tool, users received regular notifications about updates to be installed.

In Windows ME and 2003 SP3, this was replaced with Automatic updates. The automatic update allowed installation without going to the web browser. It checked for updates less frequently compared to the previous tool (once every day to be precise).

With Windows Vista came the Windows update agent which was found in the control panel. Important and recommended updates would automatically be downloaded and installed by the Windows update agent. Until the previous version, the system would restart right after a new update was installed. With windows update agent, a user could reschedule the mandatory restart that completes the update process to a different time (within four hours of the installation).
